TRAVELING BLOCK.

SBECTFIGATION forming part of Letters Patent No. 433,601, dated August 5, 1890. Application filed December 27, 1889. Serial No. 335,137- (No model.)

To all whom it may concern:

Be it known that I, ASSARIA REWRIOK, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Traveling Blocks; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of travel ing blocks for the main-sheet of vessels, and my invention consists in the novel constructian and arrangement of the traveling block hereinafter fully described, and specifically pointed out in the claims.

The object of my invention is to provide a simple and effective device of this character which will readily move from side to side, and so constructed that it willpermit the sheet to pass over from one position or direction to the other without interference.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a front elevation of my traveling block. Fig. 2 is an end view of the same.

A is the usual block rail or rod in the stern of the vessel. It is mounted in suitable supports a, and here shown as having heads a, whereby said rod is held firmly in place.

13 are independent sleeves, which are mounted and adapted to slide upon the fixed rail or rod A, one being at each end of said rod and just within the fixed supports a thereof.

0 is the block or sheave frame. This has feet 0, which are fitted over and are adapted to slide upon the sleeves B-one on each sleeve the latter being provided with end heads or flanges b, which lie just within the feet 0 of the frame. Between these end heads or flanges b is a cushion of any suitable character, here shown in the form of a spring D, encircling the fixed rod A. In the frame are the sheaves E. It will be seen that the whole top of the frame 0 is open, so that the main-sheet may readily swing from side to side as the frame moves.

The operation of the device is as follows: As the traveling block moves to the right on the rod, its right foot simply slips along the sleeve B at that end, said sleeve being held in rod, thereby compressing the intervening cushion or spring between the head or flange b of the left-end sleeve and the head or flange of the right-end sleeve. This spring therefore acts as a cushion to ease the movement of the traveling block, and when it moves to the left the reverse of this operation takes place, the spring being compressed .in that direction and limiting and easing the movement.

On account of the open character of the top of the frame 0 the main-sheet is enabled to swing from side to side without difficulty, thus avoiding the heavy and jarring swinging which takes place when the ordinary sheet-blocks are used.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with independentsliding sleeves, of a traveling or sliding sheet block having a sheave-frame the top of which is open, whereby the main-sheet may swing from side to side freely, substantially as herein described.

2. The combination of the independent sleeves mounted and adapted to slide upon the fixed rail or rod-one at each end-the sheave frame or block mounted and adapted to slide on the sleeves, and the cushion or spring intervening between the inner ends of the sleeves, substantially as herein described.

3. The combination of the independent sleeves mounted and adapted to slide on the fixed rail or bar and having the flanges or heads on their inneror adjacent ends, the sheave frameorblock having the feet mounted and adapted to slide one on each sleeve, and

the cushion or spring intervening between the flanges or heads of the sleeves, substantially as herein described. l. The combination of the independent sleeves mounted and adapted to slide upon the fixed rail or rod one at each end-and limited by the end fastenings or supports thereof, said sleeves having on their inner ends the flanges or heads, the frame or sheave IOO block having feet mounted and adapted to slide-one on each sleeve-and the cushion or spring intervening between the flanges or heads of the sleeves, substantially as herein described.

5. A traveling block for the main-sheets of ing between the inner ends of the sleeves, substantially as herein described. In witness whereof I have hereunto set my vessels, consisting of the frame G, having an hand.

open top and feet 0, the sheaves in said frame the independent sleeves mounted and sliding ASSARIA upon the fixed rail or rod-0ne at each end Witnesses:

thereof-and having inner end flanges or S. H. NoURsE, heads, said sleeves being fitted freely within H. 0. LEE.
